Rustler Peak in Oregon is a mountain and extinct volcano rising to 6,214 feet. It has been described as both a shield volcano and a stratovolcano, reflecting its volcanic origin and its place as a summit in the surrounding landscape. Its name preserves a piece of local frontier history, recalling cattle rustlers who once operated in the area. The peak remains notable for both its elevation and the way its name connects the volcanic landscape to that small fragment of regional lore.
